Underpinning

Subsidence is caused by a  variety of reasons but the most common cause is clay soils.

Many properties in the South East are constructed on Clay with insufficient foundations leading to subsidence.  This is particularly true of Victorian properties.  

There are several methods of remedying subsidence but the most common is underpinning.  Croft has extensive knowledge & experience in underpinning.

Buildings Insurance normally covers subsidence. Croft can provide a report on whether cracking is caused by subsidence prior to contacting insurance firms.  Providing the home owner with a Professional opinion with which to confront insurance firm. 

If the cracking is caused by subsidence our fees can be claimed back.

Foundations and Trees

The south East of England is covered in many areas with London Clay.  Trees affect the clay by removing water during the summer months.  This causes shrinkage of the soil and if footings are on this shrunken clay movement occurs.

We design all our footings to comply with the NHBC Guide lines for footings near trees.
